IM PROVEMENT IN, SEESAWS.

Specication forming part of Letters Patent No. 201,897, dated April 2,1878; application filed January 5, 1878.

To all lwhom it may concern:

Be itv known that I, JOHN B. TYLER, of Brooklyn, ofthe State of NewYork, have invented a new and Improved Nursery-Seesaw, of which thefollowing is a speciiication:

My inventionconsists in the arrangement of a seesaw, which can beextended when required for use, or closed up when not in use, so as tooccupy only very little space.

In the accompanying drawing, Figure I represents a longitudinal sideelevation of myimproved seesaW extended for use. Fig. II is a top viewof the same, and Fig. III is a crosssection of the box-beam.

A represents the frame or stool supporting the seesaw, made with an openjaw, B, in which a box-beam, C, turns on centers a. To the ends of thisbeam O springs D are attached,

fastened. to a central bolt, E, fixed in the framing. In the box-beam Ctwo arms, F and G, are made to slide. The sides of the box-beam areprovided with grooves n n, in which wheels s s, attached to the arms Fand G, are made to work, and through which said wheels these arms F andG are guided in their motion inwardly and outwardly. In the ends of theboxbeam pins fw are fixed, fitting into suitable holes in the under sideof the arms F and G, when the same are pulled out to their desiredextent, so as to hold said arms in this'position, lookin g the same fastwhile the seesaw is in operation. On the outer end of the arm F a seat,J, similar to a saddle, is arranged, provided with a projectingcross-bar, H, andv on the outer end of the arm G a seat, K, simi lar toa chair, is arranged, suitable to receive a girl, and provided withaprojecting cross-handle, H. This chair-seat K is made to turn partlyaround on thearm G by means of a center-pin, w, to enable seating thegirl upon the same sidewise, in a position similar to a seat upon ahorse.

When the seesaw is not in use the arms F and G are slightly liftedupward, so as to come clear of the locking-pins w, and are then movedinward, as shown in dotted lines in Fig. I, occupying thus but verylittle space.

I claim as my invention, and desire to secure by Letters Patentl. Thecombination of the frame A, with open jaw B, box-beam C, springs D, andsliding or extending arms Fl G, arranged to operate in the manner andfor the purpose described.

2. The box-beam C, provided with grooves d a n, in combination withwheels s s attached to the sides of the slidingarms F G, substantiallyas specified.

3. The pins w in the ends of the beam C, in combination with the slidingarms F and G, for the purpose set forth.

4. In combination with sliding arms F and G, arranged to operate for thepurpose described, the saddle-seat J on the end of one arm, and thechair-seat K, capable of turning on its center-pin w at 'the end of theother arm, and the projecting cross-arms H and H', substantially in themanner and for the purpose herein specilied.
